Hey Sam,
Sorry for the confusion. Maybe Nico had some customization in his test site that’s why it worked on his end. But, it does not work on my end and also one of my colleagues with only Pro, WooCommerce and WooCommerce Product Image Flipper. It works on the default WordPress theme. X and Pro have some overrides for the Shop page (FUNCTIONS/GLOBAL/PLUGINS/WOOCOMMERCE.PHP) and all or one of those overrides might not be compatible with the flipper plugin. With that said, this would need custom integration which would be outside the scope of our support.
We’re sorry we offered to check your site. I believe Nico tried to go above and beyond but troubleshooting third party plugin integration issues is really outside the scope of our support. We like to know a third party plugin’s compatibility and if we see it’s not compatible like this case, we will post it in our issue tracker or as a feature request. Even with that though, we could not promise an immediate fix nor the plugin will ever be supported as I see the overrides are made specifically for the theme’s design while the flipper plugin assumes the user is using a theme without WooCommerce overrides.
Thank you for understanding and sorry for the inconvenience.
